Was pretty awesome. Got a few pictures with guys dressed as Mando's and Stormtroopers and got some tips on what materials to use and how to make it.
Saw Stan Lee, Lou Ferrigno (The original Hulk in the TV show, and the voice of every Hulk afterwards), and Chris Hemsworth (Thor).
And I got a Bad Ass print of a Xenomorph made and signed by Rob Prior.
It was crowded as all hell, and the line went around the building, but altogether, a pretty great experience. Even saw a few people I haven't talked to in years. Neither recognized me because I was a kid when they last saw me and now I've got a big red beard. XD

And hey, for any of you Steam Punk peeps, check this guy out: http://kellysheroes.webs.com/
They guy that runs it is an old friend of my dad's, and photos just don't do his custom work justice.
